Abstract: An electronic device according to embodiments of the present disclosure may include a first wireless earphone, a second wireless earphone, and a cradle on which the first wireless earphone and the second wireless earphone are seated. The cradle may include a control device including a processor, a memory operatively coupled to the processor, communication modules configured to connect communication with an external terminal and/or communication between the first wireless earphone and the second wireless earphone according to the processor, and a power supply for charging batteries of the first wireless earphone and the second wireless earphone. The control device transmits a location finding alarm command from the external terminal to at least one of the first wireless earphone and/or the second wireless earphone in a wired communication method. In addition, various embodiments may be possible.

Abstract: A wearable device is provided. The wearable device includes a housing including a first side facing a part of a body of a user when the wearable device is worn by the user, and a second side opposite to the first side, and a sensor module disposed between the first side and the second side, the sensor module including a light-emitting unit and a light-receiving unit spaced apart from the light-emitting unit, wherein the housing includes a groove disposed between the light-emitting unit and the light-receiving unit and dent toward the second side from the first side.

Abstract: According to various embodiments, an electronic device including a housing and a detection circuit configured to output a signal indicating a submerged state on the basis of a condition associated with submergence being satisfied is provided. The electronic device also includes a plurality of terminals, a switching circuit electrically connected to the plurality of terminals, and a processor. The processor is configured to: receive the signal output from the detection circuit while the switching circuit is in a first state and output a control signal, for switching the state of the switching circuit from the first state to a second state, to the switching circuit on the basis of the received signal. The switching circuit can be configured to switch from the first state to the second state on the basis of the reception of the control signal.
